Black Onyx, a black chalcedony variety. Solid opaque black with a high polish; originally a banded chalcedony, but the term now refers to uniformly black varieties.

Where does it come from?

This batch is from Minas Gerais, Brazil.

Grade AA, black. Each piece 1-1.50 inches.

Some commercial black onyx is dyed to achieve uniform black; ours is sourced from natural-color deposits.

What is it traditionally used for?

Many people work with Black Onyx for protective practice, often placing it near doorways or carrying it for personal protection. Traditionally associated with the root chakra.

How should I care for it?

Wipe with a soft dry cloth. Mohs 6.5 to 7.

What does a crystal grade (A, AA, or AAA) actually mean?

Crystal grades reflect visual quality within a single batch. Grade A is standard quality with typical inclusions. Grade AA shows stronger color saturation, cleaner surface, and tighter sizing. Grade AAA represents the top 10 to 15 percent of any batch: exceptional clarity, consistent color, and minimal surface variation. At Beyond Bohemian, grades are assessed by Paul Oliver at point of purchase.

Will I receive the exact piece shown, or one chosen from your stock?

For bulk listings sold by weight or piece count, you receive pieces from the same batch shown in the photos. Each piece is hand-selected at the time of packing. For unique specimens listed individually, you receive the exact piece photographed. The listing will specify which applies.

Black onyx is deep, uniform black with a glassy polish when it's cut right. Most market material has been dyed for consistent color, so if the seller doesn't mention that, assume it.

Sourced directly from Minas Gerais, Brazil. Worth knowing: a lot of the black onyx on the market is dyed. What we carry is natural and untreated.

The Romans carved it into cameos, and most commercial black onyx on the market has been dyed for consistent color since naturally solid-black material is rare.

Those who work with black onyx often turn to it for a sense of groundedness when things feel uncertain, staying connected to your body and the moment, and settling into who you already are. It's traditionally linked to the root chakra. If that resonates, set one on the floor near where you sit to read or work. How you use it is up to you.

These are traditional associations drawn from historical practice. This stone is not a substitute for medical or mental health care.
